Lesson Plan

• Write balanced symbol equations for reactions and correctly attach state symbols.
• Convert balanced symbol equations into complete ionic equations by dissociating strong electrolytes.
• Identify spectator ions and simplify to net ionic equations.
• Balance equations using both atom count and charge conservation.
• Apply the procedure to acid‑base, precipitation and gas‑evolution reactions.

• Projector or interactive whiteboard
• Slide deck with worked examples
• Printed worksheet with practice reactions
• Periodic‑table handout
• Common‑ion cards (Na⁺, Cl⁻, etc.)
• Whiteboard markers and eraser

Begin with a quick “mystery reaction” challenge to spark curiosity. Review students’ prior knowledge of state symbols and balancing equations. Explain that by the end of the lesson they will be able to produce complete and net ionic equations from any balanced symbol equation.

1. Do‑now (5'): Write state symbols for a list of given formulas.
2. Mini‑lecture (10'): Recap state symbols and outline the four steps to write a symbol equation.
3. Guided practice (15'): Walk through Example 1 (acid‑base) together, completing the symbol, complete ionic and net ionic equations.
4. Partner activity (15'): Solve Examples 2 and 3, then compare answers and discuss spectator ions.
5. Whole‑class debrief (10'): Highlight common errors and reinforce the checklist for ionic equations.
6. Independent practice (15'): Worksheet with three new reactions for students to write all three equation types.
7. Exit ticket (5'): Each student writes the net ionic equation for a surprise reaction displayed on the board.

Summarise the step‑by‑step pathway from a balanced symbol equation to its net ionic form. Collect exit tickets to gauge understanding and assign a short homework task: complete ionic and net ionic equations for two additional reactions from the textbook.
